Problems with Sony DA-2400ES?

[Mpeake]

I have been noticing that my 2400es has the video blank out shortly after either (a) just turning on the receiver and video source or (b) switching from one video source to another. Short example: I am watching Sat and decide to play the PS3. Click play PS3 on my handy Logitech and input switches to PS3. Everything switches fine and I see and hear the PS3 as I should, but soon thereafter I lose the video but still have audio. Switching between inputs again fixes the problem. It is not just limited to a single HDMI input on the rcvr as I have had this happen with the SAT input as well. Also it does not happen every time. Has anyone else noticed this? I am hoping that it is an HDMI handshake issue, and not a bad HDMI board on the rcvr. Does anyone have any thoughts?
